GaussianBeam

class GaussianBeam(options1, options2)

Bases: Laser

GaussianBeam represents a TEM00 Gaussian laser beam.

Adds beam waist and center position to Laser and provides Rayleigh range and average intensity for convenience.

Example:

g = GaussianBeam(waist=[50e-6; 60e-6], center=[0;0;0], wavelength=1064e-9, power=3);
zR = g.RayleighRange;
